What is the difference between Otto and diesel cycle?

Otto cycle is used for petrol or spark ignition engine while diesel cycle is used for diesel or compression ignition engine. The main difference between Otto cycle and Diesel cycle is that in Otto cycle heat addition takes place at constant volume and in diesel cycle heat addition takes places at constant pressure.

What is the difference between heat engine and Carnot engine?

Real heat engines can only approximate the Carnot cycle, so they are less efficient than the theoretical Carnot engine. In 1857 Clausius used the Carnot cycle to create a consistent formulation of the 1st and 2nd laws of thermodynamics.

What is the difference between Carnot and Otto cycle?

A Carnot engine is, simply, a reversible engine acting between only two heat reservoirs. By contrast the Otto cycle, which has heating at constant volume, would need a whole series of heat reservoirs at incrementally higher temperatures to carry out the heating reversibly.

What is the basic difference of a Diesel and an Otto engine?

What is the difference between the ideal cycle and actual cycle of a reciprocating engine?

The largest difference between the two diagrams is the simplification of the intake and exhaust strokes in the ideal cycle. In the exhaust stroke, heat Qout is ejected into the environment. In a real engine, the gas leaves the engine and is replaced by a new mixture of air and fuel.

What is the difference between Brayton cycle and Carnot cycle?

Carnot cycle is ideal cycle for a gas turbine power plant. It contains 2 isothermal processes and two reversible adiabatic processes. Brayton cycle is actual cycle on which gas turbine power plant works. It contains two reversible adiabatic processes and two constant pressure heat rejection processes.

What is the main difference in the process that takes place during the combustion of reactants in the diesel engine cycle as compared to the Otto cycle?

The main difference that separates these two cycles is the way they supply heat to the engine to begin the ignition. Another noteworthy difference is that the Otto cycle heat occurs at constant volume, whereas the diesel cycle works on constant pressure.

What is the difference between Carnot cycle and Carnot engine?

Reversed Carnot cycle is same as that of conventional Carnot Cycle except the direction of the processes. Carnot engine is an ideal heat engine that converts heat energy into mechanical energy.

What are the characteristics of heat engine?

Key qualitative points are: (1) loop shape; (2) maximum efficiency being far below Car- not efficiency; (3) proximity of maximum efficiency and maximum power points. deterrent to operating at both high and low rates of heat input.

What is the main difference in the process that takes place during the combustion of reactants in the Diesel engine cycle as compared to the Otto cycle?

Why does diesel cycle have high efficiency compared to Otto cycle?

3. 6 Diesel Cycle. Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice.
